franck Foa AGRICULTURAL IMPLEMENTS.

To all whom. it may concern.'

lBe it. known that I, SAMUEL B. HAZARD, a citizen of the United States, residing at Peoria, in the countyof Peorla and State of Illinois, have invented certain new and useful Improvements in Trucks for Agricultural Implements; and I do hereby declare that. the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

T ns invention has reference to trucks for use more inrticularly in connection with aorieulturull ,'implements, and has 'for its oiijcct to provide a tongue-truck for use in connection with diskharrows, although the truck is of s'ueh a nature that it may be used with other and diil'erentforms of agricultural tools or machines.'

j "The invention has for a further object, a tongue-truck, including both a tongue adapted for connection with a farm implement'or tool, a v'secondi tongue having a hingedconnection with said first mentioned tongue, and with which double and swingletrees' may lbe attached; an axlehaving an oscillatory connectionwith said irst.`1nen tionedv tongue,"'wheel supports having a swivelcd connection 'with said axle, and

steering connections'between said second tongue and'said whcel'snpports.

For al further anld'full description-of the invent-ion hercinand the merits thereoand also tol acquire a'knowledge of 'thedetails of` 'construction of themeans for eecting the result;--reference is hadto the following description and drawings hereto attached.

While the'essential and characteristic features" of the invention are susce tible of modiiicatiorn still" the preferred em odiment of the invention' isi-illustrated.inthe accompanying-drawings, in which Figure l is a greatly "reduced top' plan view of my improved'tongue truck, dotted lines "indicating a position 'of the wheels when the forward tongue is' swung/fand dotted lines 'showing alsoV a diskfharrow connected with'said truck;"Fig. "2. is aI side elevation offmy'improved'truck with .the diskhar'row attachedtheretogand shown 'fin full lines; while by'dotted 'lines thetfront tongue isfshown ina raised position; Fig. 8 is an elevation looking at the rear of my 1m )roved ie. and wheels are shown in a tiltedposltion toilluatrate-how the axle may rock lnl a vertical y Speciiication of Letters Patent.

plane; Fig. 4 is a perspective view looking lat my improved truck troni the rear and to Aone side; the'near wheel having been relmoved; Fig.- 5 is an enlarged vertical longi- -tudinal sectional View as the same would appear if taken on the line (1 -(1. of Fig. 1; Fig. (il is a detail perspective of a connection in the steering mechanism; Fig. 7 is a perspective showing a modified construction of a front truck, and Fig. 8 is a detail sectional View illustrating how the body of the axle may be adjusted, by being elevated or lowered and maintained in such osition.

Like numernls of reference inticate corresponding parts throughout the figures.

No attempt has been made to illustrate in detail, the particular form of disk harrow in connectlon with which it is designed to use my improvements, nor is it thought necessary to refer particularly to the detail construction and coperation of the component parts-of a disk-harrow, as no particular claimfwill be madefon-th'e detail construction of such a harrow, except in so far as the harrow or parts thereof,` cooperate or are combined with 'my improvements.v As-was intimated in the tore part -of the specification, it is designed to employ-my improvements in connection, preferably with a disk-harrow, although it will be obvious that in connection with any agri- -cult-ural implement where it is designed to lemploy a :tongue truck, my improvements maybe applied equally as well, as to a disk- ,harrowr In'the .drawings,the axle is constructed 'preferably in truss like form, being comj posedof upper and lower bars 1 and 2, the former having its o posite ends bent downwardly as at 3, whi e the body of the latter diverges downwardly from a central point where it is connecte to the bar 1 through a hearing block 4 and the opposite ends of said 'bar 2 are also bent downwardly and secured to the portions 3 of bar 1, by bein(r bolted or otherwise secured thereto;` and secured to the )ortions 3 of the bar l are brackets 5, pre erably U shaped, providing the upper and lower laterally projecting bearing plates (i for a purpose to be explained.

lhe axle just described, has connected thereto and extending rearwardly therefrom, a tongue 7; the connection between ton ue 7 and axle, being made through a spint le 8, ,the forward end oil which hun a hearing iu lll) ' preferably, by

the block 4, mounted between the bars l and 2 of the axle; .and the relative position ofthe spindle, and the bearing b lock is maintained, inserting a Cotter-pin' 9 thiouffli the forward end of the spindle, after first `placing a washer 10 on the spindle, and a. shoulder l1, against wliicli'tlie inner face of the block 4 will bear. lVitli such a construction, it will be seen. that the `axle may accommodate itself to any unevenness of the ground over which the wheels, to be described, may travel, and the spindle is iixed against movement by the sinne being fixedly secured toA the forward end of the tongue 7 Such securing means,y comprises a bolt l2 passing up `through the spindle 8 and the tongue 7, and a U bolt is also provided, passing around theinner end of the spindle and u i through the tongue. A bearing plate 14 is inter osed between the spindle 8 and the lower fiice of the tongue, and the bolt 12,

which is used for securing the spindle 8 in place is also used, see Fig. 5, for securing a caring plate 15 to the .upper forward face of the tongue 7 the bolt 12 also serves as a v pivotal-connection fora hinge 16 which projects forward of the end of the-tongue 7 and has pivotally connected thereto at 17 avplate Asa ' 5 and a` cotter-pin 22 is lsecond tongue and bearing plates 24 throngh'which the spindles 20 are carried and said bearing plates 24 lie'` in juxtaposition to and below and-abovethe bearing plates G of the brackets-5, see Fig. 4. The brackets 23 at their lower endsr are ing yoke ortions 25 which are preferably semi-circa ar in form and when the wheels and spindles are connected up with the axle proper said semi-circular portions 25 will overlie and partially? surround vthe .inner hiihs of the wheels-19 and portions of the connection of the brackets 28 with the spindlesl 20 and the overlying portions of said brackets 23 whichl artially 4surround the hubs of the wheels and spindles, that the spindles 2O are rotated in'tlieir-bearinfrsfor Swingin vthewheels intoa osition, chown in 'dette lines -in yFig. f1.1 'H he connections Iv foroscillating'said'brackets'l and spindles 20 will nowbedescribed.;I i

llie'second'ton neto which-'reference has been made. wliiei in reality is tlio front erably f in Fig.

tongue or pole to which it is designed to at tach the double and swin le trees,is indicated as 26 and to the lower ace thereof and extending some distance along the same from its inner end is attached the forward section of the hinge between front and rear tongue sections, being the strap 18 referred to. This strap at a suitable point and for a short 'distance is bent downwardly and spaced alpart from the tongue 2G as at 27 and is s otted, as shown at 28.

yA truss frame composed of upper and lower bars 2S) and 30, is spaced some distance in front of the axle and is normally in par allel relation with said axle. The upper bar 29 of this frame is spaced the fart-liest from the bar 30 beneath the tongue 2G and is connected to said bar 30 at or near this point by the studs 31, which not only secure the bars together but retain them separated,as shown, and a bolt B2 which connects said bars centrally beneath the tongue 2G is carried up through the slot 28 in the stra 18, see Fig. 5, and is capable of having a siidable relation with said strap, lengthwise of its slot, as is apparent. The bar 29 from a point where the studs 31 connect it with the bar 30, is piefinclined downwardly toward the op osite ends of the bar 30, and at its outer ents is spaced a short distance from and is held in arallel spaced relation with the outer ents of the bar 30 by studs 33, and

connections 34 pivotally secured by bolts or other means to and between the, ends of the bars 2,9 and 30. The connections 34 are castings, or similar members which are provided with the channels or grooves 35 in their opposite faces in which are seated and secured by means of bolts 36, the outer ends of .st-raps 37, whichhave their inner ends con- Aneetedto the brackets 28, preferablyv in the i manner seen in Figs. 2, 4 and 5.

A clevis 38 constructed somewhat as shown 5 isrovided in connection with the inner end o ythe tongue 2G, with which the usualdouble tree connection maybe made. shown provided with the outwardly extend- The -ton e 26 when moved to the right,

with it will be oscillated the hinge formed `of the sections 1 Gand 18; also, the truss I n frame formed of the lbars 29 and 30, through spindles 20, sce Fig. 3. It is'tlirough this the connection of thebolt 32 with the strap 18 will be moved endwise, and through the v connection of the straps 37 between the ends of said truss frameand the brackets 23, cause saidbrackets to be oseillated and swing or turn the ground'wheels 19, through the connection established between the v.brackets 23 and the spindles 20. The axle i will accommodate itself to the unevenncss of `the 'ground by its oscillating in a vertical plane oii the outer end of the spindle 8, which has Huch a bearing in the bearing or to the eft, asvshown in dotted lines in c 5 F ig. 41 will be oscillated on the bolt 12 which serves as the pivot for said front tongue and noeases bicclr el as ellos-r for such oscillation, .and the fr nt tongue Q6, may oe raised or lowered to a considerable degree, through the pivotal connection provided between said connect n Cp? niodied construct shown. coinnosed. nrefecably. o Deir Us i 4^ 'L 1 'J-{("11' 1J' ,E or parallel sneced bags/Sn Wnicn man oe any suitable lenggt. the opposite which are gfoined in nets other sunable connections 4e?, which forni bearing' for short vertical stems provided with lateral fr extended spindles l on which may be suitably secured the ground rhecls.

lo the axle, justdescribed, is connected the forward end or a tongue i2 adapted to have connection with an implement. The connection of the tongue 42 with the axle is made through a bracket i3 which has eers dei., between which the axle is pivotally se cur to allow for vertical oscillation oi Seid axle, seid bracket has the 'further ears i5 between the forward end of the tongue e2 is disposed. 'A blocks@ is preferably secured between the bars 39 of the axle to groeide a ller for that portion of the aule where the bracket 3 V.s connected thereto.

Firotally mounted on the forward end of the tongue 42, by means of a suitable coupling, not shown, is a plete 47 which preferubly projects beyond the end of the tongue 42 und from the opposite ends of said plate extend upwardly e.. pair et spaced ears e8 and 49. To the -T'ornier, is preferably connected, the front tongue 50, which makes provision for e drop tongue in connection with the truck, and the rear end of the tongue 50 is designed, when the :iront end thereof is raised, to drop down in between the ears 49, which will serve to relieve the strain on the pivotal connection of the tongue 50 with the eers 48, when said tongue, together with the plate e7, are swung on the coupling between the plate and tongue 42, when it is designed to s-eer the wheels or operate the steering connections between the plate 47 and said Wheels. The steering connections comprise a pair of short cranks 51 which have a suitable connection with the upper ends of the spindle 4l, und to the outer ends of said cranks 5l are connected the opposite ends of a bar which has a suitable connection with the forward end of the plate 47. From the toregoing, it `will be seen that upon the swinging of tbe tongue 50, the plate i7 Will be CIK to the bar 52, which will rotate the spincorrespondingly swung und impart motion,

dies al in their bearings and turn the Wheels in the direction in which it is designed to ni Je the tongue truck.

l have made ment-ion that the tongue 7 might connected With a disk-narrow or other implement in some other wey than that illustrated, having in mind the fact that with some implements the hitch might be loner, While with others, the bitch Knight be higher; hoever/er, it is preferred to proride for such a contingency by connecting the bars l and 2 of the axle, adjustably `u'ith the brackets 5, as seen in Fig. 8.

The brackets 5 are provided with a plurality orf perioretions E13-spaced equidistent from each other, and each of said peroraons 53 in the bracket-s, when the brackets and arles are in the relative positions seen in Fig. 3, coincides with a perforation 54, in the portions 3 of the bar l, the lowestneri'orations 5 in said portions 3 of the bar always coinciding with a perforation 55 in the downwardly bent portions of the bar 2, and bolts 56, secure the brackets 5 to the bar l and theober l to the bar 2.

Fig. 8 illustrates that the axle and tongue connections have'been dropped or lowered the distance between two of the perforetions in the brackets 5, and gives a very clear idea of the manner inwhioh adjustment may be made for the purpose of Varying the height of the. bitch or the tongue v7 to ineetV the requirements in connection with rarious makes and styles of agricultural tools and implements. While the ends of the main portion of the axle are shown provided with only three openings or perforations 54 corresponding to the number shown in the brackets 5, it is understood that the extensions 3 of the ends of the axle may be made ot' any suitable length and thus enlarge the scope of the up or down adjustment of the axle and tongue 7, for the purposes explained. Y
